e14097 Background: Signet ring cell carcinoma accounts for less than 1% of all colon cancers. We examined the clinical pathological features and prognosis of signet ring cell carcinoma of colon Methods: A total of 206 patients diagnosed with signet ring cell carcinoma from 1995 to 2009 were identified from the VA Central Cancer Registry (VACCR) database.(More)
This paper introduces a new and simple statistic on noncrossing partitions that expresses each coordinate of the toric h-vector of a cubical complex, written in the basis of the Adin h-vector entries, as the total weight of all noncrossing partitions. The same model may also be used to obtain a very simple combinatorial interpretation of the contribution of(More)
200 Background: Small cell carcinoma of genitourinary system (SCC) is a highly aggressive and rare entity. The aim of the study is to characterize the clinicopathologic characteristics and evaluate the treatment outcomes of SCC in adult patients. METHODS Retrospective analysis of 732 patents diagnosed with small cell carcinoma of bladder from 1973 to 2007(More)
e14024 Background: Surgical resection of the primary tumor in the absence of metastatic disease is the treatment of choice for colorectal cancer. There is limited data evaluating surgical outcomes in the very elderly patients (≥80years). The purpose of this study was to evaluate surgical practice patterns and their effects on survival for patients ≥80 years(More)
We consider two shellings of the boundary of the hypercube equivalent if one can be transformed into the other by an isometry of the cube. We observe that a class of indecomposable permutations, bijectively equivalent to standard double occurrence words, may be used to encode one representative from each equivalence class of the shellings of the boundary of(More)
